:' us'l' u-Fwm it may concern:

llc i? known that l, Anou'n Nrnnoorln, a el wen of the United Slates, and resident of lilnauluve in the county of Milwaukee and e Tfi'alc of Wisconsin. have invented certain new and useful Improvements in Marine Sro utdmi Apparatus; and I do hereby declare that the following is a full, clear, and r ns description thereof.

My imenlion refers to wit-contained pro- )Ii and slecring apparatus, the same beespecially designed for attachment to small crafts of the row-boat type.

"ihe rimary object of, my invention is to in pyoude a simple, economical and light portab e device of the above characier capable of i :ulily assembled or dismantled and ly atlacheddo a small boat irrebpefilivQ of its shape or dimensions and adjested with relation to the draft of the boat. Pip-urine obiecls of my invention are to provide a two-part clamping; bracket, having a, wise-l clutch cmineclion. for suspending the propelling and steering apparatus, n-hcreby the elevation and angle thereof reaitive to the boat can be varied, the bracket members being in hinge coi'in'ection; s proi'ide a head constituting part of an en gin: nlieli having (:lutclrhulrs which co-act Wiiil he chuch members of the bracket, y the ap mratus isswiveled and rigidly o in a selected position; to provide in mnneclion with the engine shell or deim-hably securing an engine- .lrmisillgf sleeve. the free end of which Slaw" e ca: lhe ordinary type of propeller in i-my connection with the shaft; to proride a. practically water-tight gear casing llnil i detai' lily secured to the tree end of n. e for the reception of a propeller who", we said casing being also formed ith a pump chamber; to provide a reversible rolalory pump mechanism in drivng connection with the propeller arbor. the

mid pump mechanism being mounted withn the casing pump chamber; lo provide a, cunk-nrrving riu'ldcr-slen'l in parallel reiion with the sleeve and delachably conre -ted with the head and gear casing; to

.-rovidc revolublc tiller-carrviup clip that mounu (1 upon the head and mslidable enn iih the rudder crank elem, mid shin is orwillalcd and lastly to pro. idc all o." the :bovc uwnlmocd parts toi I ihei" to; :l.e engine shell with means for 311 section to more clearly illustrate the struc' tural features, the section being indicated by ines l-l of Figs. 2, 3 and 4; Fig. 2, a rear sectional View of the same, the section being indicated by line 2--2 of Fig. 1; Fig. 3, a. detailed cross-section of the head and its connected steering mechanism, the view being upon an enlarged scale and the section indicated by line 3--3 of Fig. 1; Fig. 4, an enlarged sectional face view of the pump mechanism, the section being indicated by line 4-4 of Fig. 1; Fig. 5, a detailed sectional view of a. rudder-stem showing a he hole slotted ear that extends from the head, into which car the upper end of said stem is journaled, and Fig. 6, a detailed cross-section of a two-part clamping-bracket showin a hinge connection between its members.

veferring by characters to the drawings, 1, 1, represent the cylinders comprising part of an engine-sl1ell provided with the usual water-jackets 2. hlounted in the cylinders are pistons 3 having pitmen 4, which are connected to cranks of an engineshal't 5. The upper end of the engine-shaft is journaled in a cap 6 that isdelachably fitted to an aperture in the crank-casino which. forms part of the engine-shell, the sald shaft being provided with the usual fly-wheel 7. Filled to a lower opening in the crank-casing is the flanged portion b of a head 9, which head scl'xcs as a support for the engine-shell and is bored to also form a bearing for the engiuwshaft. The lower end of the head is cmmlerborcd for the reception of one end of a sleeve ll). The lower end of the sleeve has delachably secured thereto a gear-casing l l. the same being held in position by screws lb", which pass through apertures in the shell and are in threaded union'with corresponding apertures in a shank 11 forming the Immilz m" i1 how! i) has (3% "110 Gum-nuns, :1 he i'zm uf wlu h caving.
